I've taken a good number of longbeards using a "Shaggie Suit" and a set of decoys.  My favorite setup is a logging road ambush where I sit back in the brush with the male decoy positioned facing me in the hopes that a gobbler will address him head on and fan.  When he fans I draw and take him up the anal opening - your basic "Texas Heart Shot" if you will:^)  The most effective head I've used on turkeys to date is the huge Simmons Treesharks.

Hahaha Gary, I suppose that would make a great aiming point.

I was able to draw last year in a blind, but the bird was clearly a hen... so I let down.  She was about 10 ft from me and never saw me draw.  I think blinds work, but you HAVE GOT TO also assume they can see you in them and wait until they are turned, head down, looking away, or concentrating on a decoy before you can draw.  I think it is also good to be able to hold your draw for a few secs incase you need the time for the bird to not be looking before release.  

Best of luck!  And check out "Turkeys 101" its thread I started to discuss this same thing about a month ago... great advice on there : )

Get back into some heavy pines with a thick canopy on a bright day on a field edge.. I took 2 that way...  Even missed the first one and had to get another arrow nocked... Zipped him at 30 yards on the 2nd arrow!  The bright sun in the field makes it dificult to see Into the dark woods!

Trees and remaining motionless work good, and you don't end up carting around all that extra gear in and out of the woods.

To really hunt gobblers you have to be mobile.I use a ghillie.
